Dr. Soumit K. Behera currently works at the Plant Ecology and Climate Change Science Division. His group has been working in the field of forest biomass and productivity assessment, monitoring and modelling using field measurements. His group primary focusing on long-term studies for understanding carbon dynamics in tropical deciduous forests.
Dr. Behera is experienced in forest ecology, field measurements for biomass and productivity studies using silvicultural and sensor measurement techniques. As a leading team member, he has assessed, modelled and validated the biomass and productivity in three forest types in an Indian tropical deciduous forest. He has also generated inputs for 11 eco-physiological variables from in-situmeasurements to run Biome-BGC, a production efficiency model. He has standardized and established a new indirect method for LAI estimation in tropical deciduous forest, and formulated forest type-wise aboveground biomass equations using LAI as variable. He has served as a nodal Principal Investigator of an investigation entitled ‘Exploratory studies on climate change and adaptation of species complexes’ during 2008-2012, wherein long-term ecological observation plots were established in three forest communities at Katerniaghat Wildlife Sanctuary in northern India, for understanding carbon dynamics in tropical deciduous forests.

Tropical deciduous forest plays disproportionately important role in carbon sequestration and storage, with complex regulation mechanism by local environment (microclimate) and community structure. Long term ecological research provide continuous data for systematic understanding of the ecosystem structure and function at population/community level, thereby provide inputs for better carbon modeling and studying long term effect of changing climate.For very first time, the forest understory was studied for diurnal and seasonal variations in five microclimatic parameters; i.e. photosynthetically active radiation (PAR), air temperature, soil temperature, ambient CO2 and air absolute humidity in tropical deciduousforests.Assessed the above ground biomass and biomass carbon at species level in three forest communities i.e. dry mixed, sal mixed and teak plantation using DBH allometric models from long term ecological research (LTER) plots and established humidity and air temperature were the two major microclimatic variables supporting higher carbon sequestration using PCA and multivariate analysis.
We performed Biome BGC simulation for three forest communities (dry mixed , sal mixed and teak plantation) having distinct tree species compositions, different carbon assimilation rates and microclimate, using daily meteorological data at Katerniaghat Wildlife Sanctuary, India. Out of 39 eco-physiological parameters, 11 major eco-physiological parameters were parameterized specific to above three forest communities.We simulated the monthly NPP and LAI for three forest communities and further validated the model-derived NPP and LAI with observed NPP and LAI data.The model revealed that NPP attained peak during the autumn season (particularly in September) for all 3 forest types, while plants have maximum canopy cover leading to optimum photosynthetic gain.This study validated the applicability of Biome BGC to simulate LAI and NPP for tropical deciduous forest in Indian sub-continent. NPP was simulated very well as compared to observed data, however, LAI was underestimated in current Biome BGC simulation.
Assessment of forests soil CO2 efflux is essential for understanding carbon exchange process between atmosphere and the terrestrial biosphere as part of the global carbon budget and further predicting it’s change in response to climate change. Soil CO2 flux is extremely dynamic, and is controlled by spatio-temporal changes in soil temperature, water content, pH, carbon in soil. The soil CO2 efflux is also controlled by type of vegetation cover, under canopy microclimate and soil physico-chemical properties. We studied the diurnal soil CO2 efflux patterns in three forest communities (dry mixed, Sal mixed and Teak plantation) in an Indian tropical deciduous forest site of Katerniaghat Wildlife Sanctuary located in Terai. We also tried to investigate the interaction of abiotic factors on soil CO2 efflux in Indian tropical deciduous forest.
